неопределенная ссылка на std:: ios base::Init::Init()

Я работаю над изучением ООП с C++ и имею проблему. Я уверен, что это проблема с распределением памяти, но, похоже, не могу обойти ее. Любая помощь будет очень признательна.

    #include <iostream>
    #include "Box.cpp"

    using namespace std;

    int main(){
        Box *box = new Box;
        return 0;
    }

Мой Класс Box...

    #include <iostream>

    using namespace std;

    class Box{

        private:
            double width;
            double height;
            double perimeter;
            double area;


        public:
            Box(){
                cout << "Box created" << endl;
            }

            ~Box(){
                cout << "Box Destroyed" << endl;
            }

            double getWidth(){
                //
                return this->width;
            }

            double getHeight(){
                //
                return this->height;
            }

            double getArea(){
                //
                return this->area;
            }

            double getPerimeter(){
                //
                return this->perimeter;
            }

            void setWidth(double w){
                //
                this->width = w;
                if(!this->height){
                    computeSetArea(this->width, this->height);
                    computeSetPerimeter(this->width, this->height);
                }
            }

            void setHeight(double h){
                //
                this->height = h;
                if(!this->width){
                    computeSetArea(this->width, this->height);
                    computeSetPerimeter(this->width, this->height);
                }
            }

        private:
            void computeSetArea(double w, double h){
                //
                this->area = w*h;
            }

            void computeSetPerimeter(double w, double h){
                //
                this->perimeter = (w * 2) + (h + 2);
            }
    };

Я использую gcc и выполняю:

    gcc Box.cpp client.cpp -o mainfile

после такого я получаю эту ошибку.
